Ensuring Easy Access to the Router
If your Cisco 7304 router is installed in a standard 19-inch, 4-post or 2-post rack, cables from other
equipment in the rack might obstruct access to the front of the router. Also, rack power strips or other
permanent fixtures may obstruct access to the router. Review the following guidelines to ensure easy
access to the front of the router when it is installed in a rack. If the router is not installed in a rack, or if
you already have clear access to the front of the router, proceed to the “Powering Down the Router and
Disconnecting Input Power” section on page 4-2.
Use the following guidelines to ensure easy access to the front of the router when it is installed in a rack:
•
Ensure that you have at least 3 to 4 feet (.9 to 1.2 meters) of working space at the front of the router.
•
If cables from other equipment in the rack fall in front of the router, carefully gather the cables
(using care not to strain them) and use cable ties to anchor them away from the front of the router.

•
If access to the front of the router is partially blocked by a power strip or some other permanent rack
fixture, detach the router from the rack and carefully slide it forward until there is enough clearance
to remove the network services engine from the router. Detailed steps for detaching the router from
the rack are contained in the “Removing the Network Services Engine” section on page 4-4.
Powering Down the Router and Disconnecting Input Power
The following sections describe how to remove power from an AC-input power supply and a DC-input
power supply:
Note
•
Powering Down an AC-Input Power Supply, page 4-2
•
Powering Down a DC-Input Power Supply and Removing the DC-Input Leads, page 4-3
If you have two NSEs in the Cisco 7304 router in a high availability configuration and want to remove
one, do not power down the router. Simply remove the NSE and insert a new one, because high
availability provides for the other NSE to take on the processing tasks for the router.
Powering Down an AC-Input Power Supply
Note
Before powering down the router, use the copy running-config startup-config command to save the
router’s running configuration to nonvolatile random-access memory (NVRAM) or another file
system.
The Cisco 7304 power supply switches have a standby symbol (a broken circle with a line through it)
and an on symbol (|) on the power switch. If only one power supply is installed in the router, the standby
symbol means off, as there is no other power supply to take over its function. If two power supplies are
installed, one is turned on, and the other power supply switch is set to the standby position, as it will be
activated automatically if the primary power supply fails.
To power down the AC-input power supply to the Cisco 7304 router, complete the following steps:
Step 1
Place the power switch to the standby position (broken circle with a line through it).
Step 2
Observe the following items:
Step 3
Note
•
The green INPUT OK LED and FAN OK LED on the power supply turn off.
•
The fans in the power supply stop operating.
•
All LEDs turn off.
Remove the cable from the AC-input power receptacle.
When powering off the router, wait 30 seconds before powering it on again.
This completes the procedure for powering down an AC-input power supply on a Cisco 7304 router.

Powering Down the Router and Disconnecting Input Power
Powering Down a DC-Input Power Supply and Removing the DC-Input Leads
Warning
Before completing any of the following steps, and to prevent short-circuit or shock hazards,
ensure that power is removed from the DC circuit. To ensure that all power to the power supply is
OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit
breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Note that the power to the power supply should be off, not necessarily all power to the router. A
DC-Input power supply can be running when another power supply or fan module is being removed
or replaced.
Warning
When installing the unit, the ground connection must always be made first and disconnected last.
Note
Before powering down the router, use the copy running-config startup-config command to save the
router’s running configuration to NVRAM or another file system.
The Cisco 7304 power supply switches have a standby symbol (a broken circle with a line through it)
and an on symbol (|) on the power switch. If only one power supply is installed in the router, the standby
symbol means off, as there is no other power supply to take over its function. If two power supplies are
installed, one is turned on, and the other power supply switch is set to the standby position, as it will be
activated automatically if the primary power supply fails.
To power down the DC-input power supply to the Cisco 7304 router and remove the DC-input power
leads from the DC-input power supply, complete the following steps:
Step 1
Place the standby switch on the DC-input power supply in the standby position.
Step 2
Ensure that power is removed from the DC circuit by turning off the circuit breaker or switch providing
power to the DC-input power supply.
Step 3
If necessary, remove the cable tie that secures the DC-input power line input leads and ground lead to
the power supply faceplate. Save the cable tie.
Step 4
Using a 1/8-inch flat-blade screwdriver, loosen the screw above the –DC power line input lead
receptacle and pull the lead from the connector. Repeat this step for the +DC power line input lead and
the ground lead.
Note
The color coding of the DC-input power supply leads depends on the color coding of the DC
power source at your site. Typically, green or green/yellow is used for ground. Make certain
the lead color coding you choose for the DC-input power supply matches lead color coding
used at the DC power source.
This completes the procedure for disconnecting DC-input power and removing the DC-input power leads
from the DC-input power supply.

Step 6
Gently slide the network services engine all the way into its chassis slot until you feel the connectors
seat with the router midplane. Push the locking levers to lock the network services engine in place.
Step 7
Seat the network services engine in the router midplane by tightening its captive installation screws with
a number 2 Phillips or a 3/16-inch flat-blade screwdriver.
Note
The network services engine is not fully seated in the router midplane until you tighten its captive
installation screws.
Step 8
If you removed power supplies from the router, replace the power supplies. (See the “Reconnecting Input
Power and Powering Up the Router” section on page 4-19 when replacing a power supply in a Cisco
7304 router.)
Step 9
If you slid the front of the router out of the rack, slowly guide the router back into the rack.
Step 10
Use a 3/16-inch flat-blade screwdriver to tighten the screws that secure the router to the front mounting
strips of the rack.
This completes the procedure for inserting the network services engine in a Cisco 7304 router.
For information on reconnecting the cables, go to the “Attaching Multimode and Single-Mode Optical
Fiber Cables” section on page 4-15, the “Attaching the Mode-Conditioning Patch Cord” section on
page 4-17, and the “Reconnecting AC-Input Power” section on page 4-19 or the “Reconnecting
DC-Input Power” section on page 4-20.
Removing and Replacing the SDRAM SODIMM
This section explains how to remove and replace the SDRAM SODIMM main memory modules on the
network services engine. Other than the CompactFlash Disk, the SDRAM SODIMM is the only
physically replaceable memory type on the NSE-100.
Caution
The DDR-SODIMMs on the NSE-150 motherboard are configured in a “butterfly” configuration,
meaning the SODIMMs are designed to not lay flat on the motherboard like the other components. The
DDR-SODIMMs should not be forced to lie flat on the board. Forcing the DDR-SODIMMs to lie flat on
the board can cause damage to the SODIMM or the NSE-150 motherboard.
These NSE-150 SODIMMs are also not field-replaceable.
The SDRAM SODIMM is the main memory module for the Route Processor on the NSE-100. The
SDRAM SODIMM stores the configuration and routing tables for non-IP traffic. Cisco IOS software
executes from main memory, and the Route Processor is responsible for forwarding all non-IP traffic and
analyzing routing protocols. The advantage of upgrading the SDRAM SODIMM is to allow the NSE-100
to establish more sessions with communicating devices. The SDRAM SODIMM might also need to be
replaced to correct a problem being caused by the SODIMM.
Note
Use only Cisco-supported SDRAM SODIMMs.

Removing a SDRAM SODIMM on the NSE-100
This section provides a procedure for removing the SDRAM SODIMM on the NSE-100.
Caution
The DDR-SODIMMs on the NSE-150 motherboard are configured in a “butterfly” configuration,
meaning the SODIMMs are designed to not lay flat on the motherboard like the other components. The
DDR-SODIMMs should not be forced to lie flat on the board. Forcing the DDR-SODIMMs to lie flat on
the board can cause damage to the SODIMM or the NSE-150 motherboard.
These NSE-150 SODIMMs are also not field-replaceable.
Follow these steps to remove the existing SDRAM SODIMM:
Step 1
Power down the router and disconnect input power, if it hasn’t already been done.
See the “Powering Down the Router and Disconnecting Input Power” section on page 4-2 and follow
the directions for powering down the router and disconnecting input power.
Step 2
Remove the NSE-100, if it hasn’t already been removed.
Go to the “Removing the Network Services Engine” section on page 4-4 and follow the instructions for
removing the NSE-100. Then return to this section.
Step 3
Place the NSE-100 on an antistatic mat or pad and ensure that you are wearing an antistatic device,
such as a wrist strap.
Step 4
Locate the SODIMM. See Figure 4-6.
Step 5
Release the spring latches from the SODIMM, and release the SODIMM from the socket (see
Figure 4-6).
To prevent ESD damage, handle the SODIMM by the card edges only (see Figure 4-7). Place the
removed SODIMM on an antistatic mat and store it in an antistatic container.

This completes the SODIMM removal procedure. Proceed to the next section to install the new
SODIMM.
Inserting a SDRAM SODIMM on the NSE-100
This section provides a procedure for inserting the SODIMM on the NSE-100.
The synchronous dynamic random-access memory (SDRAM) on the NSE-100 is contained in one small
outline dual in-line memory module (SODIMM) (see Figure 4-6).
Caution
SODIMMs are sensitive components that are susceptible to ESD damage. Always wear an antistatic
wrist strap when working with SODIMMs.
Handling a SODIMM

Figure 4-7
Follow these steps to install the new SODIMM:
Step 1
Remove a new SODIMM from the antistatic container.
Step 2
Hold the SODIMM with the connector edge (the metal fingers) away from you. Wear an antistatic wrist
strap and handle SODIMMs by the edges only; avoid touching the memory modules, pins, or traces (the
metal fingers along the connector edge of the SODIMM). (See Figure 4-7.) Ensure that the metal
fingers of the SODIMM align properly with the SODIMM receptacle.
Step 3
Hold the sides of the SODIMM between your thumb and index finger (see Figure 4-7).
Step 4
Tilt the SODIMM to approximately the same angle as the receptacle, and insert the pin edge into the
connector.
Caution
Note that these instructions are for the NSE-100.
The DDR-SODIMMs on the NSE-150 motherboard are configured in a “butterfly” configuration,
meaning the SODIMMs are designed to not lay flat on the motherboard like the other components. The
DDR-SODIMMs should not be forced to lie flat on the board. Forcing the DDR-SODIMMs to lie flat on
the board can cause damage to the SODIMM or the NSE-150 motherboard.
Furthermore, the DDR-SODIMMs on the NSE-150 are not field-replaceable, so they should not be
removed from the NSE-150 motherboard.

Installing and Using the CompactFlash Disk
Caution
When inserting the SODIMM, use firm but not excessive pressure. If you damage a socket, you will have
to return the NSE-100 to the factory for repair.
Step 5
Press the SODIMM down until it is secured by the spring latches.
Step 6
When the SODIMM is installed, check both alignment holes on the SODIMM and ensure that the
spring latch is visible. If it is not, the SODIMM is not seated properly. If the SODIMM appears
misaligned, carefully remove it and reseat it in the socket. Push the SODIMM firmly back into the
socket until the spring latches snap into place.
This completes the SDRAM SODIMM installation procedure. To reinstall the NSE-100 in the chassis,
see the “Inserting the Network Services Engine” section on page 4-7.
Installing and Using the CompactFlash Disk
This section provides instructions for installing, removing, and using CompactFlash Disks in the
Cisco 7304 router.
On the NSE-100 and NSE-150, CompactFlash Disks provide storage space for your configuration files,
Cisco IOS software images, and so forth.
This section includes the following subsections:
•
Product Description, page 4-11
•
Installing and Removing the CompactFlash Disk, page 4-13
Product Description
CompactFlash Disks are Flash memory-based devices that conform to the PC Card (formerly PCMCIA)
standard, and that present an AT Attachment (ATA) interface to the system. This interface complies with
the ANSI ATA Interface Document X3T13.1153 D Rev. 9 specification.
The CompactFlash Disk is more flexible than linear Flash memory because the CompactFlash Disk has
controller circuitry that allows it to emulate a hard disk and that automatically maps out bad blocks and
performs automatic block erasure. Further, the CompactFlash Disk provides the capability to allocate
noncontiguous sectors, which eliminates the need for the squeeze command (previously required with
linear Flash memory cards).
The CompactFlash Disk is a Type-2 PC Card device. The CompactFlash Disk provides increased
Flash-based memory space for storage of system configuration files, Cisco IOS software images, and
other types of system-related files. Table 1-3 provides memory information for the CompactFlash Disk.
The Cisco IOS File System feature provides a single interface to all file systems your system uses:
•
Flash memory file systems—CompactFlash Disks, onboard Flash memory, linear Flash memory
cards
•
Network file systems—File Transfer Protocol (FTP), Remote Copy Protocol (rcp), and TFTP
•
Any other endpoint for reading or writing data—NVRAM, the running configuration, ROM, raw
system memory, system-bundled microcode, Xmodem, Flash load helper log, modems, and BRI
MUX interfaces

Note
The color coding of the DC-input power supply leads depends on the color coding of the DC power
source at your site. Typically, green or green/yellow is used for ground. Make certain that the lead color
coding you choose for the DC-input power supply matches the lead color coding used at the DC power
source.
Warning
Before completing any of the following steps, and to prevent short-circuit or shock hazards, ensure
that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker
on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and
tape the switch handle of the circuit breaker in the OFF position.
Warning
When installing the unit, the ground connection must always be made first and disconnected last.

Chapter 4
Removing and Installing the NSE
Reconnecting Input Power and Powering Up the Router
Note
This product relies on the building’s installation for short-circuit (overcurrent) protection.
Ensure that a listed and certified fuse or circuit breaker, 35A minimum 60 VDC, is used on
all current-carrying conductors.
To reconnect DC-input power to a Cisco 7304 router, complete the following steps:
Step 1
Ensure that the DC power line input leads are disconnected from the power source.
Step 2
If necessary, use a wire stripper to strip approximately 0.55 inch (14 mm) from the DC power line input
and ground leads.
Note
Do not consolidate the strands by soft soldering. Use 12 AWG (2.5mm) copper wire only.
Step 3
Insert the stripped end of the ground lead all the way into the ground lead receptacle on the DC-input
power supply and tighten the receptacle screw using a 1/8-inch flat-blade screwdriver. (See Figure 4-13.)
Step 4
Insert the stripped end of the +DC lead all the way into the lead receptacle and tighten the receptacle
screw using the same 1/8-inch flat-blade screwdriver. Repeat this step for the –DC lead.
Note
Make sure that the entire stripped end of each lead is inserted all the way into its receptacle. If any
exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove
the lead from the receptacle, use the wire stripper to cut the stripped end of the lead, and repeat Step 2
through Step 5.
Step 5
After tightening the receptacle screw for the ground and DC power line input leads, secure the leads to
the power supply faceplate. Use a cable tie to secure the three leads.
Note
When securing the ground and DC power line input leads to the power supply faceplate, leave a small
service loop in the ground lead to ensure that it is the last lead to disconnect from the power supply if a
great deal of strain is placed on all three leads. (See Figure 4-13.)
Step 6
Connect the ground and DC power line input leads to the power source.
Step 7
Repeat Step 1 through Step 6 if a second power supply is installed.
This completes the steps for reconnecting DC-input power to a Cisco 7304 router. Proceed to the
following section, “Powering Up the Router.”

Verifying a Successful Boot
Powering Up the Router
To power up a Cisco 7304 router complete the following steps:
Step 1
Check for the following:
– Each line card is inserted in its slot, its respective line card levers are in the locked position, and
the locking thumbscrews are tightened.
– Empty line card slots have a blank line card installed for cooling and correct airflow.
– All network interface cables are connected to the Gigabit Ethernet GBIC module cables.
– All network interface cables are connected to the line cards.
– A CompactFlash Disk is installed.
– Each DC lead is connected and secured to the power supply faceplate with a cable tie.
– Each DC lead is connected and secured to the power source (DC-input power supplies only).
– Ensure that the tape (that you applied earlier) is removed from the circuit breaker switch handle,
and power is restored by moving the circuit breaker handle to the on (|) position (DC-input
power supplies only).
– The console terminal is turned on.
Step 2
Plug the AC power supply cable in to the AC power source. Turn the power switch on. Repeat if a second
power supply is installed.
Step 3
Listen for the fans; you should immediately hear them operating.
Step 4
During the boot process, observe the system LEDs.
Note
If the system detects a corrupted FPGA image, you will be prompted to download a golden FPGA image
from ROM 0. The system will then reset automatically and will restart the boot process. The download
is necessary to continue the boot process.
Step 5
Observe the initialization process. When the system boot is complete (a few seconds), the network
services engine begins to initialize the line cards. During this initialization, the LEDs on each line card
behave differently (most flash on and off). The STATUS LED on each line card goes on when
initialization is completed, and the console screen displays a script and system banner similar to the
following:

This completes the procedures for connecting input power and powering up the router. This also
completes the procedure for installing the network services engine in a Cisco 7304 router.
Verifying a Successful Boot
The router boots at the point when both the NSE and the power supply are properly installed. If the
following steps occur, you have verified that a successful boot process has occurred.

OL-3967-01
Chapter 4
Removing and Installing the NSE
Verifying a Successful Boot
Step 1
Verify that the green INPUT OK LED on the power supply turns on.
Step 2
Listen for the fans; you should immediately hear them operating.
Step 3
During the boot process, observe the system LEDs. The LEDs on most of the line cards and the NSE
should go on and off in irregular sequence. Some may go on, go out, and go on again for a short time.
Step 4
Observe the initialization process. When the system boot is complete (a few seconds), the network
services engine begins to initialize the line cards. During this initialization, the LEDs on each line card
behave differently. The STATUS LED on each line card goes on when initialization is completed, and
the console screen displays a script and system banner.
If the system fails to boot properly, or if the console terminal displays a checksum or memory error,
check the following:
•
Check the NSE by making sure it is properly seated in the midplane. If the NSE is not properly
installed, reinstall the NSE and reboot the system for an installation check.
•
Check the power supply. If the power supply is not properly installed, reinstall it, and reboot the
system for an installation check.
•
Check the SODIMM by looking straight down on it and then at eye level. If a SODIMM appears to
stick out or rest in the socket at an odd angle, remove the SODIMM and reinsert it. Then replace the
network services engine and reboot the system for another installation check.
If after several attempts the system fails to restart properly, contact a service representative for
assistance. Before you call, note any error messages, unusual LED states, or other indications that might
help solve the problem.
